We could evaluate the expression 2(20+7) + 3(50+2) using the traditional order of operations, or we could use the distributive p
KonstantinChe [14]

Answer:

It is more efficient to use order of operations because with the distributive property, you would have to multiply four times and add once (5 things to do), whereas with order of operations, you have to add twice and multiply twice (4 things to do).

Someone please help​
dedylja [7]

Answer:

1. y = -2x + 5

2.  y = 3/5x + 5

3. y = -4/5x - 4

4. y = - 1

5. yes

6. yes

7. yes

8. no

Step-by-step explanation:

1.   (4,-3) parallel to y= -2x

     -3 = -2(4)+b

     b=5

2. (-5,2) parallel to y = 3/5x

    2= 3/5(-5)+b

     b=5

3. (-5,0) -4/5x

   0 = -4/5(-5)+b

    b = -4

4. (-4,-1)

    y= -1

5. yes

6. yes

7. yes

8. no

  • Same slope = parallel ex. y = -5x +7, y = -5x +12
  • opposite reciprocal  = perpendicular ex. y = -5x +7, y = 1/5x + 12
  • to find "b" with slope and point

          (x,y)  y = mx + b

          plug in the y value and x value in the eqaution and m=slope, solve for b

Find the surface area of the shape below.
almond37 [142]

Answer:

54m^2

Step-by-step explanation:

Each square has a equal sides, which is 3m

in order to find the surface area, it's

Formula : Base x height = Area

The total surface area would be all the area's added together

3x3=9cm^2

so each square is 9m^2

there are 6 squares so

9+9+9+9+9+9=54m^2

or you can do 9x6=54m^2
